Grizzly Buffer for 3M wheels?

Bench grinder

3/8 bore is too small for scotchbrite wheels. You want 1/2" arbor.
I recommend one 3M on one side and a buffing wheel on the other. One slip and a part is toast. Yep. I hit the wheel on the opposite side. Buffing wheel won't damage a part and it helps balance the grinder. I used one 7A wheel for the whole build.
